CGA was Andrea’s first published music project who had a focus on musical carpets. Lengthy pieces using sounds as the main driver and mean of composition, as opposed to a more orthodox approach, to evoke feelings, draw atmospheres, and for storytelling.

In 2012, Aner Andros succeeded CGA. On one hand, with a passage marked by a concentration on internal variety and abstractions, moving from obscure lengthy pieces to denser sound-design-focused music. On the other hand, the approach (composing with sound design) and the goals (atmospheric storytelling) remained true to this day.
